Description
Describe the bug
I am using Image v3.4.0 , I used drawLine to draw lines, it has always been 1px
The same result was obtained using the DrawPixelLine of https://github.com/Intervention/image/issues/1298
Code Example
$image->drawLine(function (LineFactory $line)use($listHeight) {
$line->from(980, 20); // starting point of line
$line->to(980, $listHeight-20); // ending point
$line->color('#723e4b'); // color of line
$line->width(5); // line width in pixels
});

Research direction
Start at the GD implementation reached by drawLine() and reproduce the supplied PHP example with GD 2.1.0 compatibility. Done means the requested width of 5 produces a visibly wider line under GD, with the corrected behavior verified by the project's tests.
